The steps of glycolysis between glyceraldehyde-3-phosphate and 3-phosphoglycerate involve all of the following except: a. atp synthesisb. utilization of pic. oxidation of nadh to nad+.d. the formation of 1,3-bisphosphoglycerate. e. catalysis by phosphoglycerate mutase.

Option(C)- Oxidation of NADH to NAD+H

Explanation:In glycolysis at the step between formation of 3-phosphoglyceraldehyde from glyceraldehyde 3-phosphate, NAD+H is reduced to form NADH(where NAD stands for nicotinamide-adenine dinucleotide) which means a hydrogen atom is added in NAD forming NADH.This enters in elecron transport chain (etc) in mitochondrial membrane which ultimately helps in production of ATP.Hence all other options are true except option C.

Result: Therefore option C is the correct answer.
